That's right. There's no such thing as OSAS. It's clearly stated, you go to hell if you chose to follow sin.
That's right. OSAS advocates think they're going to heaven and nothing can stop them. So they live in a false security without any effort to repent and turn from sinful nature.
Paul tells us, we are to change and transform ourselves through Christ till we become a new man, one that no longer sin.
Romans 12:2 (ESV) Do not be conformed to this world, but be transformed by the renewal of your mind, that by testing you may discern what is the will of God, what is good and acceptable and perfect.
2 Corinthians 5:17 (ESV) Therefore, if anyone is
in Christ, he is a new creation. The old has passed away; behold, the new has come.
1 John 3:9 (ESV) No one born of God makes a practice of sinning, for God's seed abides in him, and he cannot keep on sinning because he has been born of God.
You have to be
IN CHRIST to be transform. You have to be
IN CHRIST to be a new creation. You have to be
IN CHRIST to be born again. You have to be
IN CHRIST to stop sinning. You have to be
IN CHRIST to be saved.
Bottom line is this, once saved always saved is absolutely false if you're once a sinner always a sinner.
You have to change your old carnal nature, it's that simple. If you can't overcome this transformation, you won't be saved. It's written all over in Revelation 2-3.
